My 2007 Volvo XC90 has developed some mysterious ailments that no one has been able to explain. First, it goes along fine for months not losing oil (we check the oil regularly), then suddenly the oil goes down quickly. We use synthetic oil. It also goes along fine on antifreeze, bu suddenly loses it and the light comes on. No one can find any leaks. Then, after the front struts were replaced on my 2007 Volvo XC90, there has been a noise that sounds like stretching rubber when you turn the steering wheel. It only occurs on warm days, however. The mechanic where the car is serviced said it may be a leak in the power steering but then couldn’t find one.
What’s up with this car?

losing oil and anti-freeze intermittently just screams head gasket to me. Yours may be on the way out. This will get worse, not better. Keep an eye on your oil and coolant levels. Have a pressure test done on the cooling system. That may expose the gasket problem.

As for the steering noise, ignore it for now, you have bigger problems.
